Letters Patent No. 113,491. dated April 11, 1871.

IMPROVEMENT lN Fl-LTERS.

The Schedule referred to in these Letters Patent and making parl: of the same.

To all whom if may concern:

l Be it known that I, JAMns BROWN, of the city and county of San Francisco, State of California, have invented an `Improved Filterer; and I do hereby declare the following description and accompanying drawing are suicient to enable any person skilled iu the art or science to whiehfi't most nearly appertains to Ina-ke and use my said invention or improvements without further invention or experiment..

My inventio'rurelatesto an improved filterer or strainer, through which liquids of all kinds, but more particularly liquors, can be passed'7 and in their pas# sage be deprived of any undissolved or .foreiguparticles or matter which they may contain.

To make my flterer I take from th'ree to tive sheets of unsized paper and place them in any suitable vessel, and dampen or wet them with a small quantity of the liquid which is to be filtered. I then Inacerate them, by any suitable means, untilthey have been reduced to a pulp.

The vessel is then illed with the liquid and thoroughly mixed with the pulp.

Au inverted "conical bag 4or filter, which may be made of flannel, muslin, orother porous or weft Inaterial', is then suspended over the receiving-tank and the contents of the first-named vessel poured into the bag.

"The 'drawing off of the liquid in the bag will causo through one of these tilters before it becomes clogged' up, when it can be cleaned by washing it in clean wa'- ter until the adhering pulp is removed; after which, if V `not wanted for immediate use, it can be hung up to dry; but lwhen used again the same operation above described is repeated. 4

By the use of this lter any liquid can be readily and thoroughly cleansed, but more particularly wines anddiquors, which, after passing through the iilterer, will be of extraordinary purity, and greatly improved in quality and color.

Having thus described-my invent-ion,

\Vhat I claim, aud'desire to secure by Letters Pat ent, is-

A ltering-vessel or sack constructed as above described, and lined with pulped paper, substantially in the manner set forth.

In witness whereof. I have hereunto set my hand and seal.
